Multigrid Methods for (Multilevel) Structured Matrices Associated with a Symbol and Related Application
When dealing with large linear systems with a prescribed structure, two key ingredients are important for designing fast solvers: the first is the computational analysis of the structure which is usually inherited from an underlying infinite dimensional problem, the second is the spectral analysis which is often deeply related to a compact symbol, again depending on the infinite dimensional problem of which the linear system is a given approximation. When considering the computational view-point,...
